Decimal separator localization

[gualandd]

Hi, I’m using multiple entity row in HA but I see that the decimal separator is not in locale form but in english form: I live in Italy and we use comma for decimals, not the dot.
Is possible to add the localization to have the right number separation?

Agree, same issue for me in DE.
Would be very much appreciated if the hass locale format could be considered.
